The DAT_OLD file extension is a type of backup file utilized by Minecraft. When the program is running, it creates files that players save their data in, which are done in the form of a DAT file. This file contains information about the level, such as stored items crafted items, mining progress, and even objects stored in chests. When the game is saved, the current DAT file is backed up to create a DAT_OLD file. This provides an extra layer of protection from lost progress and protects the original DAT file from being corrupted.
Usage of DAT_OLD
The DAT_OLD file extension does not have any native program associated to it. The purpose of this backup file is solely for use within the Minecraft game. It serves as an additional layer of protection from any potential loss of progress when the game is saving or if the main DAT file is corrupted. Since there is no other practical use for this type of backup, many users are more inclined to delete the files.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DAT_OLD) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DAT_OLD extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DAT_OLD file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DAT_OLD extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DAT_OLD extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DAT_OLD file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DAT_OLD file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DAT_OLD file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DAT_OLD file) will be extended to the maximum.
It is also good to check
- if the .DAT_OLD file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
